       =================================================================== 
       Case of two/several Timers
       **************************
       1. If TIM2 is used as master to other timers use the following functions:
          - TIM2_SelectOutputTrigger()
          - TIM2_SelectMasterSlaveMode()
       2. If TIM2 is used as slave to other timers use the following functions:
          - TIM2_SelectInputTrigger()
          - TIM2_SelectSlaveMode()
          
       Case of Timers and external trigger (TRIG pin)
       ********************************************       
       1. Configure the External trigger using TIM2_ETRConfig()
       2. Configure the Slave Timer using the following functions:
          - TIM2_SelectInputTrigger()
          - TIM2_SelectSlaveMode()
